Further, we also describe an implementation, based on a novel data structure called aggregated bitmap, that allows the LR(T) algorithm to be realized at line ...
Internet routers and switches need to maintain millions of (e.g., per prefix) counters at up to OC-768 speeds that are essential for traffic engineering.
Oct 22, 2024 · This paper removes this bottleneck in [1] by proposing a counter management algorithm called LR(T) (Largest Recent with threshold T) that avoids ...
What is more remarkable is that this improvement in effi- ciency is achieved with a CMA that is extremely simple and con- sumes only a small fraction of bits ...
Varghese, “Efficient implementation of a statistics counter architecture ... • A simple and efficient counter management algorithm for hy- brid SRAM ...
Maintain an array of counters in fast memory (SRAM). • For each packet, a counter is chosen via hashing, and incre- mented. • No attempt to detect or resolve ...
Oct 22, 2024 · We present both precise and statistical (probabilistic) counters that are nonblocking and provide dramatically better scalability and accuracy ...
Our results indicate that a statistics counter can be built with a DRAM of access time 5 1.2 ns, a DRAM memory bandwidth of 1.25 Gb/s and 9 Mb of SRAM. 11.
Missing: Efficient implementation
Apr 30, 2023 · A naive implementation of the counter in the relational database uses a lock (mutex). The lock must be acquired before the count is incremented.
